太子参“3414”肥效试验研究

RADIX PSEUDOSTELLARIAE 3414 Fertilizer Efficiency Test Research

为探索氮、磷、钾肥施用量与太子参产量之间的关系,构建太子参施肥模型,在施秉县开展太子参"3414"测土配方施肥田间试验,对太子参肥料不同配比、产投比等一系列试验数据进行统计分析,初步建立了太子参N、P、K肥料效应模型,确定经济效益最高的处理为:N 75 kg/hm2、P2O590 kg/hm2和K2O 120 kg/hm2,为施秉县太子参施肥提供依据。

To explore the relationship between the yield of RADIX PSEUDOSTELLARIAE and the fertilizer dosage of N,P,K,construct RADIX PSEUDOSTELLARIAE fertilization model,RADIX PSEUDOSTELLARIAE ＂3414＂ soil measuring fertilizer field test was carried out in Shibing County,a series of test data such as different ratio of RADIX PSEUDOSTELLARIAE fertilizer,input-output ratio were statistically analyzed,the effect model of RADIX PSEUDOSTELLARIAE N,P,K fertilizer was established.The highest economic benefit of treatment was N 75 kg/hm2,P2O5 90 kg/hm2,K2O 120 kg/hm2,which will provide basis for RADIX PSEUDOSTELLARIAE fertilization in Shibing County.
